改错题

Three years ago I failed a important exam in my life and became a student in an ordinary school. Disappointing as I felt at the shabby campus and the poorly-equipped classroom, but I found the teachers patient and considerate. Besides, I enjoyed the friendly atmosphere on class. I decided to make best of it. I work hard and got along well with my teachers and classmates. Whenever I had difficulties, they were seldom available. Soon, I became one of the top student in my class, which greatly increased my confident and got me motivated.

My experience tells me that it is not what you are given but how you make use of it which determines who you are.
